157845 ÷ 7 
The aim is to understand the frequency of 7 in 157845.

Step 1:
7 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 7

Advancing to step 2:
15 divided by 7 is 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 14 from 15, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 7

Let's proceed to step 3:
If we divide 17 by 7, we get 2 and a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 14 from 17 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 7

Advancing to step 4:
7 can be fit into 38 5 times, resulting in a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 225.0
Subtract 35 from 38 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 7

Moving on to step 5:
If we divide 34 by 7, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 2254.0
Subtract 28 from 34 to get 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 7

Advancing to step 6:
If we divide 65 by 7, we get 9 and a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 22549.0
Subtract 63 from 65 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 22549.2
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
When dividing 60 by 7, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 22549.28
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
If we divide 40 by 7, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 22549.285
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 22549.2857
If we subtract 49 from 50, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 11:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 22549.28571
If we take 7 away from 10, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
When dividing 30 by 7, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 22549.285714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 13:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 22549.2857142
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
If we divide 60 by 7, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 22549.28571428
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 22549.28571428, and the remainder is 4e-09.
